Application filed September 11, 1914. Serial No. 861,260.

To all whom it may concern:

Be it known that I, JOSEPH STRETCH, a citizen of the United States, residing at Freeport, in the county of Nassau and State of New York, have invented new and useful Improvements in Building Construction, of which the following is a specification.

This invention relates to wall constructions and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide a concrete wall construction consisting of sections having means wherebv the sections may be securely held together to constitute the wall structure. means being provided for forming window and door openings in the sections when desired.

Another object of the invention is to provide a wall section which .is cheap to manufacture or construct the said section including steel studs which extend the full length thereof and which are located at the side edges of the section. These studs are connected together by cross irons and furring strips and the concrete is located between these studs and completely surrounds the cross irons and in one form may surround three sides of the furring strips and in another form extend to one side only of the furring strips. Furthermore the section may be provided with a paper or felt lining if desired and the sections are provided at their longitudinal edges with grooves in which cement may be inserted after the sections are positioned upon a foundation or other support to form a wall of a building. The invention possesses other objects and advantages which will be better understood as the description thereof progresses.

In the accompanying drawings :Figure 1 is a perspective view of several studs connected together by the cross irons and furring strips and in position to receive between them the cement to form thewall sections. Fig. 2 is a detailed sectional view of parts of Fig. 1 cut on the line 2-2 thereof. Fig. 3 is a sectional view of a completed wall section showing the same in position as molded and the section being cut on the line 3- 3 of Fig. 2. Fig. l is a vertical sectional view of one of the wall sections showing the same mounted upon a foundation. Fig. 5 is a horizontal sectional View of a portion of the wall structure formed of the sections and cut on the line 55 of Fig. 4. Fig. 6 is a perspective view of an end portion of one of the wall sections. Fig. 7 is a side elevation, with parts broken away, of a wall section showing a window or door frame therein. Fig. 8 is a horizontal sectional view of the section as shown in Fig. 7 Fig. 9 is an edge elevation of a frame for forming a raised concrete casing around a door or window opening. Fig. 10 is a horizontal sectional view of a portion of the wall showing the frame as illustrated in Fig. 9 in position upon the wall. Fig. 11 is a perspective view of an end portion of a crowning strip which may be used within the wall structure. Fig. 12 is a similar view of a footing strip which may be used in the wall structure.

In carrying out the invention strips 1 are laid flat upon the ground at suitable distances apart and strips 2 are placed on edge upon the upper surfaces of the strips 1. Studs 3 of channel iron or steel are placed upon the inner portions of the strips 1 and the ends of the said studs abut against the inner surfaces of the strips 2. Furring strips 5 are placed. upon the lower flanges of the studs 3 and tie rods 6 are connected with the uppermost flanges of the stu'ds3. When the parts have been connected together as above indicated the space between the strips 1 and the furring strips 5 is filled with sand as indicated at 7 in Fig. 3. In this instance the sand extends up to a level with the upper surfaces of the furring strips 5 however if it is desired to inclose the said furring strips in concrete the upper level of the sand 7 is at the lower surfaces of the furring strips 5. Parting strips 8 are placed between the vertical surfaces of adjacent studs 3 as shown in Fig. 1 of 'the drawing and the upper edges of the said strips 8 are at the same levelas the upper edgesof the said strips 2. The upper portions of the parting strips 8 are provided with enlarged heads 9 which are intended to form grooves at the side edges of the sections as will be hereinafter explained.

After the parts have been assembled as hereinbefore described they constitute a mold and the concrete cement indicated at 10 is poured into the mold and is worked down until the upper surface of the said material 10 is flush or in the same plane as section of concrete material does not extend to the lower edges of the studs 3 and consequently the said studs 3 may be bolted togetheras at 11 when the wall sections are placed in upright position upon the foundation indicated at 12 in Fig. 4. When the cement concrete 10 is placed between the strips 9 and the studs 3 the said material completely envelops the tie rods 6 as indicated in Fig. 3 and thus the said rods serve as means for holding the studs 3 at the edges of the wall sections properly spaced from each other. WVhile the wall section is in a horizontal position upon the ground and be fore the cement concrete 10 hardens the upper surface thereof may be finished in any desired manner and thus when the material hardens the wall section is completed.

By reason of the fact that the parting strips 8 are provided at their upper edges with heads 9 the said heads form grooves 13 at the side edges of the wall sections and when the wall sections are placed in vertical position upon the ground these grooves may be filled with cement indicated at 14 whereby the joints between the wall sections are closed.

After the Wall sections have been formed upon the ground as above indicated they are separated from each other and the parting strips 8 are removed. The wall sections are; then placed in upright ends on a foundation 12 as shown inFi'g. 4 and the inner portions of the studs. 3 are connected together by meansof the bolts 11. Thus the sections of the wall are effectually secured together and the space between the furring strips 5 may serve as air compartments in the completed wall. The furring strips 5 may be used for supporting laths or any other finish applied to the inner surface of the wall. If desired a lining 15 of paper, felt .or other suitable material may be placed upon the upper surfaces of the furring strips 5 and upon the upper surface of the sand 7 as shown in Fig. 3 and the cement concrete 10 may be poured upon the said lining. This lining of course adheres to the cement concrete and when the sections are 4 the lining 15 gives a suitable finish to the inner surface of the cement concrete.

If it is desired to provide window or door openings in any of the wall sections rough window or door frames indicated at '16 in Figs. 7 and 8 are placed between the studs 3 and the cement concrete 10 is poured between the studs and lower ends of the said frames. Finished window or door frames (not shown) may be inserted in the rough frames 16 when the wall sections are erected in position upon the foundation.

positions upon their placed in-upright position as shown in against the upper and frame 16 before the cement material 10 hardens and a frame 18 shown in Figs. 9

and 10 is placed about the frame'17 but spaced from the'same. The material 10 is then finished between the frames 17 and 18 and will form a bead standing out from the door or window opening as best indicated in Fig. 10 of the drawing. A footing strip 19, best shown in Figs. 4 and 12 of the drawing may be placed in the foundation 12 and secured to the studs 3 by means of bolts 20. This will provide means for holding the lower portions of the wall sections in place upon the foundations.

Rafters 21 may rest wholly at their end portions upon the upper ends of the strips or partially rest thereon as shown in Fig. 4 of the drawing and head strips 22 are interposed between the end portions of the rafters 21 and .the upper ends of the wall sections and bracket strips 23 are located under the end portions of the rafters 21 and are secured to the studs 3.

Therefore it will be seen that the method of con'structing the wall sections of rein forced concrete is a departure from the usual method of forming such sections and the more the sections may be securely connected together whereby a durable building is provided and at the same time afireproof structure is had. v

Having described the invention what is I claimed is zy A wall section comprising a slab of concrete material, studs-located at the opposite edges of the slab and extending the full length thereof, said studs having at their 1. longitudinal edge portions flanges disposed at the same side of the intermediate portion of the stud, said studs at one edge portion being embedded in the slab and having opposite edge portions projecting beyond the 1-] face of the slab, the flanges at the projecting? portion of'the studs being spaced from the slab and disposed parallel with the face thereof.

In testimony whereof I affix my signature 12 in presence of two witnesses. 7
